Abstract

Distributed-verifier zero-knowledge (D-ZK) proofs give a means for proving statements on data held distributedly across multiple parties. Concretely, there are multiple verifiers who each hold pieces of the input x, and zero knowledge must additionally guarantee that subsets of verifiers do not learn about x beyond their original knowledge. In this talk, we will introduce the notion of D-ZK proofs, briefly survey known constructions, and present recent developments using information-theoretic D-ZK machinery to achieve low-overhead compilers for attaining general secure computation with security against malicious adversaries.

Based on joint works with Dan Boneh, Henry Corrigan-Gibbs, Niv Gilboa, Yuval Ishai, and Ariel Nof.
